{title:Transpose of string variable dataset}

{p 8 29 2}
{cmd:sxpose, clear}
[{cmd:force format(}{it:format}{cmd:) firstnames destring}] 


{title:Description}

{pstd}
{cmd:sxpose} transposes a dataset of string variables, so that observations
become variables, and vice versa. It is a rough and ready utility: use
circumspectly. 


{title:Remarks}

{pstd}
{cmd:sxpose} is destructive. Your existing dataset will disappear. The 
compulsory {cmd:clear} option is intended to remind you of that. 

{pstd} 
The number of variables allowed in Stata is very much less than the 
number of observations allowed. See help on {help limits}. In 
addition, with even moderate numbers of observations, you may 
run into memory problems when trying to transpose a dataset. 
See help on {help memory}. 


{title:Options} 

{pstd}{cmd:clear} is a required option, flagging that you are aware 
that the current dataset will be cleared from memory. 

{pstd}{cmd:force} specifies that the transpose should go ahead 
even though the dataset contains numeric variables. Numeric values
will be coerced to string using the format %12.0g or whatever numeric 
format is specified by the {cmd:format()} option. You may lose some precision, 
especially in non-integer values, when you do this. 

{pstd}{cmd:format()} specifies a numeric format to use in coercing 
numeric values to string. See above. 

{pstd}{cmd:firstnames} specifies that the first variable (first 
column) in the existing dataset is to be treated as a set of variable
names for the variables in the transposed dataset. This first column 
will not appear as the first observation in the new dataset. Any 
values that are not legal variable names will be lost. 

{pstd}{cmd:destring} specifies that {cmd:destring, replace} will
be run on the new dataset in an attempt to convert variables that 
are unambiguously numeric in content to numeric. No force will be applied. 
See help on {help destring}.
